Trying to understand exactly what you want here... you want the Preview
button to display the preview in a separate window? This can be done
with client-side javascript, but can get tricky.

You probably want to make sure that the form is successfully validated
first, which means using fd:submit. This also makes opening the preview
in a new window difficult, since you don't know beforehand if the
validation will be successful (open a new window) or not (redisplay the
form w/errors in the same window).
I implemented a similar Preview function just recently, but it displays
the preview in the same window as the form (actually inline on the same
page as the form).

If it's just a question of how to get the contents of the "xml" member
streamed into a pipeline's generator, you can do that via the module source:
<map:match pattern="preview-pipeline">
<map:generate src="module:flow-attr:xml" />
<map:transform ... />
<map:serialize />
</map:match>
